DEBUG PORT UNLOCK problem

Hi,

    Use the latest version of LM Flash Programmer. You can download that at the TI website.

    Make sure that drivers are installed for your Tiva kit. Select Fury, DustDevil, TM4C123 and TM4C129 Classes and then press unlock. A window will pop-up prompting you to reset your board.

I tried many a times but it promting a message"failed to unlock connected device"...

please help me out....

Hi Sushil,

     Are you using the latest LM Flash Programmer version?

     If you are receiving the message "failed to unlock connected device" means there is some sort of problem or your board does not need to be unlocked.

    To know that your board does not need to be unlocked, load a known working example program. If you are able to load and run the known working example program then your board is usable again. The cause of the problem might be the last program you loaded at your board.

Hi 

actually what happened is yesterday the connecting micro USB port of my TIVA broke....i get it soldered from an electronic shop.. but when i m loading my code in it ,its raising an error..**ERROR** unable to find target........what else i can do sir...

Hi Sushil,

     Possible that the micro USB port that has been fixed is still not okay. In that case you need to verify connections.
